The interrupting curve drops as voltage rises: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V (–).
Above that it derates gradually: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C (–). If the enclosure ambient runs hot, use the 70 °C figure for the BOM line. The frame measures 70 mm deep by 101.6 mm wide by 130 mm high (–) — standard 4-pole MCCB footprint, no surprises on the DIN rail or gland plate. Maximum power loss is 19.2 W, which matters for thermal rise in a sealed enclosure. Front protection is IP40; the body is not rated for washdown.
